You need to set them both as DS0 (hopefully that is marked on the
drives - it should be).  Then enable J301 (that's the "DF1 is present"
jumper) by closing it (put the jumper onto both pins).

Now connect the DF0 floppy to the end of the floppy cable (the
connector with the twist in the ribbon) and DF1 to the other
connector.

I'm not clear on which drive is being used as DF0 and which as DF1?

For the drive with the six pins, it should look like this when the
jumper is set correctly:

     . . .
     . ._.

The one with three pins should, AFAIK, look like this when set
correctly:

     . ._.


OTOH, I've never seen an Chinon Amiga floppy drive with only three
pins, all that I've ever seen have had six pins, so are you absolutely
sure that this FB354-A drive is actually an Amiga drive?  I've got
spare FB354-A and FB354-E floppy drives here and both have six pins
(as do the drives in my A1010 and A1011 external drive cases).


Good Luck.
